Understanding the order in which React's useEffect hooks are executed can prevent unexpected behaviors in component rendering. The article explains the React Fiber architecture and the traversal algorithm that leads to child components’ effects being committed before their parent components, despite the parent being rendered first. This knowledge is crucial for managing complex component structures effectively.

An ESLint plugin called "eslint-plugin-react-you-might-not-need-an-effect" helps developers identify unnecessary useEffect hooks in React code, enhancing code readability and performance. It offers rules to avoid common pitfalls, making it especially beneficial for both new and experienced React developers. The plugin can be easily integrated into projects with a simple installation and configuration process.
